1. Associated Bodywork & Massage Professionals The Muscular System Anatomy and Physiology Flash Cards

2. Associated Bodywork & Massage Professionals Directions The first slide asks a question. The second slide answers the question. Use these slides like flash cards to test your core knowledge.

3. Associated Bodywork & Massage Professionals Question Name the three types of muscle tissue and their classifications.

4. Associated Bodywork & Massage Professionals Answer 1.Skeletal muscle = striated and voluntary 2.Cardiac muscle = striated and involuntary 3.Smooth muscle = non-striated and involuntary

5. Associated Bodywork & Massage Professionals Question What are the dark bands in cardiac muscle tissue called?

6. Associated Bodywork & Massage Professionals Answer Intercalated disks

7. Associated Bodywork & Massage Professionals Question What is the origin of a muscle?

8. Associated Bodywork & Massage Professionals Answer The muscle attachment to a stationary bone.

9. Associated Bodywork & Massage Professionals Question The attachment to a moveable bone is called the ______.

10. Associated Bodywork & Massage Professionals Answer Insertion

11. Associated Bodywork & Massage Professionals Question What do tendons do?

12. Associated Bodywork & Massage Professionals Answer Tendons connect muscle to bone.

13. Associated Bodywork & Massage Professionals Question The microscopic structure of a muscle consists of specialized contractile cells called muscle fibers. Each muscle fiber is filled with two structures called thick and thin myofilaments. What are the names for the thick and thin myofilaments?

14. Associated Bodywork & Massage Professionals Answer Thick=myosin Thin=actin

15. Associated Bodywork & Massage Professionals Question What is a sarcomere?

16. Associated Bodywork & Massage Professionals Answer The contractile unit of a skeletal muscle.

17. Associated Bodywork & Massage Professionals Question Explain the sliding filament theory.

18. Associated Bodywork & Massage Professionals Answer During contraction, the actin and myosin in a muscle fiber attach to each other by forming bridges acting as levers to pull the myofilaments past each other. Calcium must be present.

19. Associated Bodywork & Massage Professionals Question What does adenosine triphosphate (ATP) do?

20. Associated Bodywork & Massage Professionals Answer It provides energy for muscle cells.

21. Associated Bodywork & Massage Professionals Question What are the functions of skeletal muscle?

22. Associated Bodywork & Massage Professionals Answer Movement Posture or muscle tone Heat Production

23. Associated Bodywork & Massage Professionals Question In providing movement, skeletal muscle have prime movers (agonists), synergists, and antagonists. Please define.

24. Associated Bodywork & Massage Professionals Answer 1.Prime movers (agonists): carries out the action. 2.Synergists: supports the prime mover. 3.Antagonists: muscles with actions opposite of those of the prime movers.

25. Associated Bodywork & Massage Professionals Question We can maintain an upright position during standing, sitting, etc., because of a specialized skeletal muscle contraction called ______.

26. Associated Bodywork & Massage Professionals Answer Tonic contraction

27. Associated Bodywork & Massage Professionals Question What is a motor unit?

28. Associated Bodywork & Massage Professionals Answer A single motor neuron and all the skeletal muscle cells it innervates.

29. Associated Bodywork & Massage Professionals Question The minimal level of stimulation required to cause a fiber to contract is called the ______.

30. Associated Bodywork & Massage Professionals Answer Threshold stimulus

31. Associated Bodywork & Massage Professionals Question What is muscle wasting?

32. Associated Bodywork & Massage Professionals Answer Atrophy

33. Associated Bodywork & Massage Professionals Question Looking at a cross section of a muscle belly, many cylindrical structures called fascicles can be seen. Fascicles are bundles of ______.

34. Associated Bodywork & Massage Professionals Answer Muscle fibers

35. Associated Bodywork & Massage Professionals Question Once stimulated by a threshold stimulus, a muscle fiber will contract completely. This response is called ______.

36. Associated Bodywork & Massage Professionals Answer All or none
